Commercial Gas Boilers

84% efficient, low-nox hot water supply boilers

Features

A. O. Smith Genesis® boilers offer everything you could ask for in a non-condensing boiler. They provide the highest possible 84% thermal efficiency, outstanding venting flexibility, space-saving stackable design and a new, advanced Energy Management Control (EMC) system. Genesis models are available for installation indoors (GW Series) or outdoors (GWO Series).

NEW EMC-5000 ENERGY MANAGEMENT CONTROL

Patent pending

Controls every electrical boiler function, including pump operation and main burner ignition, delivers precise temperature management, with ±1º accuracy

Display panel shows current operating status and fault readings in easy-to-understand English instead of confusing numeric codes

Display also shows temperature setpoints, outlet temperature, current inlet/outlet differential (T) and tank temperature

Help screens assist in boiler setup and explain control options

Included remote temperature sensor when mounted in the storage tank allows the tank temperature to be set and monitored at the boiler

TWO-STAGE GAS FIRING SYSTEM

Twin gas valve firing system prevents short cycling and ensures smooth operation, saves fuel and extends boiler life

Prevents short cycling when demand is low, delivers maximum output when demand is high

LOW-NOx OPERATION

Meets or exceeds Texas and California SCAQMD Rule 1146.2 air quality standards

COPPER FINNED-TUBE HEAT EXCHANGER

Designed for maximum durability and serviceability

Copper is lightweight for easier handling and immune to thermal shock

Removable headers allow easy inspection of waterways

SPACE-SAVING DESIGN

Smaller footprint versus other horizontal copper fin-tube boilers

Optional stack rack allows one unit to be stacked on top of another, doubling output within the footprint of a single unit

MEETS ASHRAE/IESNA 90.1-2004

FIVE-YEAR HEAT EXCHANGER LIMITED WARRANTY
